VENUS: an ultra-faint galaxy hosting the metal-poor type II supernova at Witnessing the initial metal enrichment with extremely frequent core-collapse supernovae?
Yoshihisa Asada, Seiji Fujimoto, Joseph F. V. Allingham +50
The paper reports the discovery and detailed study of a type IIP core‑collapse supernova (SN Eos) at redshift 5.13, whose ultra‑faint, strongly lensed host galaxy is extremely meta…
VENUS: Strong-lensing model of MACS J1931.8-2635 -- revealing the farthest multiply imaged supernova
Joseph F. V. Allingham, Adi Zitrin, Vasily Kokorev +42
We present a parametric strong-lensing model for the galaxy cluster MACS J1931.8-2635 (), accompanying the detection of the spectroscopically confirmed SN Eos at $z = 5…
Origins of the UV continuum and Balmer emission lines in Little Red Dots: observational validation of dense gas envelope models enshrouding the AGN
Yoshihisa Asada, Kohei Inayoshi, Qinyue Fei +2
We present a statistical study on the origins of the UV continuum and narrow/broad emission lines in little red dots (LRDs), presumably involving active galactic nuclei (AGNs). Lev…
Little Red Dot Host Galaxy Black Hole Star: A Gas-Enshrouded Heart at the Center of Every Little Red Dot
Wendy Q. Sun, Rohan P. Naidu, Jorryt Matthee +30
The central engines of Little Red Dots (LRDs) may be ``black hole stars" (BH*s), early stages of black hole growth characterized by dense gas envelopes. So far, the most direct evi…
Other red dots: A possible GLIMPSE of normal AGB stars at Cosmic Noon through extreme lensing
Lukas J. Furtak, Adi Zitrin, Erik Zackrisson +18
We report the discovery of four extremely faint () red point sources in recent ultra-deep JWST/NIRCam images of the strong lensing galaxy cluster Abell…
A Fleeting GLIMPSE of N/O Enrichment at Cosmic Dawn: Evidence for Wolf Rayet N Stars in a z = 6.1 Galaxy
Danielle A. Berg, Rohan P. Naidu, John Chisholm +18
We present the discovery of extreme nitrogen enrichment by Wolf Rayet nitrogen stars (WN) in the metal-poor (~10% Z_odot), lensed, compact (R_eff ~ 20 pc) galaxy RXCJ2248 at z=6.1,…
